Are you seeing this error in the MyWorks Sync log when attempting to sync an order to QuickBooks Online?
Error:9331: [Invalid bundle entry in SalesItemLineDetail, Invalid bundle id "x" passed to SalesItemLineDetail.ItemRef. Please use GroupLineDetail with bundles.]
This error can be encountered if the WooCommerce order contains a bundled product, and a CHILD bundle line item in the WooCommerce order is mapped to a bundle product in QuickBooks.
We have an excellent doc on support for mapping bundled products here - where we recommend that either only the parent product should be mapped, or only the child products should be mapped.
1. Visit MyWorks Sync > Map > Products / Variations to check the mapping of the child bundle products in the order in question. Make sure that if they are mapped to QuickBooks products, that the QuickBooks products are not bundle products.
2. You can then try pushing the order over at MyWorks Sync > Push > Order to confirm it syncs successfully.
